Why do you check !p after assigning to nid? I assume it's because we
might have reached the end of the command line, ie. p == NULL, but we're
still adding memory to the last node? If so it's a it's a little subtle
and deserves a comment I think.

The reason that we check for !p after assigning node id is that, in
case we create fake NUMA nodes, we want nid to be the fake numa node
id and not the real node id or in the non NUMA case, node id 0.

The if (!p) checks to see if we do have more arguments to parse.
 

Otherwise this looks pretty good.

Thanks!

cheers
